PEX EVOH Oxygen Barrier Pipe Production Line

This pipe production line is used to produce 3 layer type PE-Xb EVOH oxygen barrier pipes, diameter range 16-32mm. The extrusion mould and extruder screw are special designed as per cross-linking feature of raw material.

Through years technology upgrading and practical experience gathering from customers' feedback, the production speed of the line has upgraded from 15m/min, up to 30m/min.

Machine Design Features:

1)Three layer EVOH co-extrusion die head is special designed as per cross-linking feature of PEX pipes, and also EVOH pipe structure. With little modification, same die head can use to produce single layer pipe also.

High quality 40Cr steel mould, processed by imported CNC machinery; The tip and die mould surface are chrome painted, which can effetively increase its hardness, reduce friction force, and easy to clean.

2) Gravimetric material doser system is equipped as an option, to ensure produced pipe quality. The benefits of the system is to stable the pipe production process and improve the product quality consistency, decrease pipe waste rate, save unnecessary material consumption, realize the precisely control for accurate thickness and high speed production.

3) Specail designed vacuum tank, with two chamber structure, which is better for sizing effect of EVOH pipe making.

The vacuum degree can also be automatically ajusted by PLC system. Requied vacuum data is directly set on PLC, then the vacuum degree will be automatically adjusted, to ensure the stable of the system vacuum condition.

4) Fully auto coiler or semi-auot coiler can be choosen. The fully auto coiler can cut the pipe and change new coil automatically, together with a pipe accumulator.

what's more, increasing intelligence of the line, the automatic strapping and unloading function can also be added.
